Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, in particular to a positioning device for processing square tubes used in photovoltaic brackets. Background Technique

[0002] Photovoltaic brackets are used to set up solar panels. Photovoltaic brackets are assembled and set up by several square tubes, and the square tubes are bent from zinc-magnesium aluminum plates or other composite materials. When the existing device replaces different bending dies during the bending of the produced square tubes, the bending die and the bending knife are prone to deviation in the vertical direction. As a result, when the bending knife presses the plate onto the bending die, the bending effect is not good.

[0003] The existing patent (publication number: CN216881180U) proposes a post-positioning device for a bending machine, which includes a workbench and a top plate. Telescopic columns are arranged at the four corners of the bottom of the workbench, and support columns are arranged at the bottoms of the telescopic columns. Rectangular blocks are fixedly connected to both the left and right sides of the workbench. A second rectangular block is movably connected to the top of the rectangular block. A bending die is arranged on the opposite side of the second rectangular block. A bending device is arranged on the front of the top plate. When the second hydraulic cylinder is started to drive the second hydraulic rod, the second hydraulic rod expands and contracts to drive the second rectangular block to move upward. At the same time, the worker rotates the disc, the disc drives the round shaft to rotate, and the round shaft rotates to drive the bending die to rotate, so as to achieve the effect of replacing the bending groove.

[0004] The above-mentioned post-positioning device for the bending machine adopts the solution that the worker rotates the disc, the disc drives the round shaft to rotate, and the round shaft rotates to drive the bending die to rotate to achieve the effect of replacing the bending groove. The problem with this solution is that it solves the problem of replacing the bending groove of the bending machine, and does not solve the problem that due to the deviation between the bending die and the bending knife in the vertical direction, when the bending knife presses the plate onto the bending die, the bending effect is not good. Therefore, we propose a positioning device for processing square tubes used in photovoltaic brackets to solve the above problems. Content of the Utility Model

[0005] The utility model provides a positioning device for processing square tubes used in photovoltaic brackets, which solves the technical problem of poor bending effect during the current processing of square tubes.

[0006] To solve the above technical problems, a positioning device for processing square tubes used in a photovoltaic support provided by the utility model includes a base. A workbench is fixed on the top of the base. A side support platform is fixed on the top of the base and on one side of the workbench. A pressing mechanism is arranged above the workbench, and the pressing mechanism is fixed on the side support platform. Slide grooves are formed on both sides of the top of the workbench. A first bending die, a second bending die, and a third bending die are slidably arranged in the slide grooves. Fixed blocks are fixed on both sides of the top of the workbench and parallel to the slide grooves. The fixed blocks and the pressing mechanism are on the same vertical line. Fixing bolts are threadedly inserted into the fixed blocks. Positioning blocks are fixed at both ends of the first bending die, the second bending die, and the third bending die. The fixing bolts penetrate through the fixed blocks to fix the positioning blocks and make the positioning blocks and the fixed blocks on the same horizontal line.

[0007] Preferably, positioning screw holes are formed in the positioning blocks. A positioning plate is fixed on the top of the positioning block and extends along one side close to the positioning screw holes to the top of the fixed block.

[0008] By adopting the above technical solution: Since positioning screw holes are formed in the positioning blocks, the fixing bolts on the fixed blocks can fix the positioning blocks. The positioning plate is fixed on the top of the positioning block and extends along one side close to the positioning screw holes to the top of the fixed block, so that the positioning plate can be flush with the calibration block on the fixed block, thereby determining whether the positioning blocks and the fixed blocks are on the same horizontal line.

[0009] Preferably, a calibration block is fixed on one side of the fixed block away from the slider.

[0010] By adopting the above technical solution: Since a calibration block is fixed on one side of the fixed block away from the slider, it is convenient to determine the positioning accuracy between the positioning blocks and the fixed blocks through the calibration block.

[0011] Preferably, sliders are fixed on both sides of the bottoms of the first bending die, the second bending die, and the third bending die. The sliders are clamped in the slide grooves.

[0012] By adopting the above technical solution: Since sliders are fixed on both sides of the bottoms of the first bending die, the second bending die, and the third bending die, and the sliders are clamped in the slide grooves, the first bending die, the second bending die, and the third bending die move on the slide grooves, achieving the effect of replacing the bending dies.

[0013] Preferably, the pressing mechanism includes a lifting column and a folding cutter. One end of the lifting column is fixed on the side support platform, and the end of the lifting column away from the side support platform is fixedly connected to the folding cutter.

[0014] Adopt the above technical solution: The pressing mechanism includes a lifting column and a folding cutter. One end of the lifting column is fixed on the side support table, and the end of the lifting column away from the side support table is fixedly connected to the folding cutter. When the lifting column presses down, the folding cutter presses down, so that the plate arranged on the bending die is bent, and the bending effect is good.

[0015] Preferably, bending grooves are provided at the tops of the first bending die, the second bending die, and the third bending die.

[0016] Adopt the above technical solution: Since bending grooves are provided at the tops of the first bending die, the second bending die, and the third bending die, when the folding cutter presses down on the plate, the plate bends at the bending grooves, thus achieving the bending effect.

[0017] Preferably, the depth of the bending groove provided on the first bending die is greater than the depth of the bending groove provided on the second bending die, and the depth of the bending groove provided on the second bending die is greater than the depth of the bending groove provided on the third bending die.

[0018] Adopt the above technical solution: Since the depth of the bending groove provided on the first bending die is greater than the depth of the bending groove provided on the second bending die, and the depth of the bending groove provided on the second bending die is greater than the depth of the bending groove provided on the third bending die, the plate can be bent at different bending angles to meet the production requirements.

[0019] Preferably, the first bending die, the second bending die, and the third bending die are connected to the positioning block in a clamping manner, and the fixing block is welded to the workbench.

[0020] Adopt the above technical solution: Since the first bending die, the second bending die, and the third bending die are connected to the positioning block in a clamping manner, it is convenient to replace the bending die. The fixing block is welded to the workbench, so that the fixing block is firmly connected to the workbench, and thus the positioning block and the bending die can be firmly fixed.

[0021] Compared with the related art, the utility model has the following beneficial effects:

[0022] 1. Compared with the traditional bending machine positioning device, the utility model is provided with a fixed block, a fixing bolt, a positioning block and a positioning screw hole. A pressing mechanism is arranged above the workbench. Sliding grooves are formed on both sides of the top of the workbench. A first bending die, a second bending die and a third bending die are slidably arranged in the sliding grooves. Fixed blocks are fixed on both sides of the top of the workbench and parallel to the sliding grooves. The fixed blocks and the pressing mechanism are on the same vertical line. A fixing bolt is threadedly inserted into the fixed block. Positioning blocks are fixed at both ends of the first bending die, the second bending die and the third bending die. The fixing bolt passes through the fixed block to fix the positioning block and make the positioning block and the fixed block on the same horizontal line. When replacing the bending die, since the fixed block and the pressing mechanism are on the same vertical line, only need to align the positioning blocks at both ends of the bending die with the fixed block, and then screw the fixing bolt into the positioning screw hole, so as to fix the bending die directly below the pressing mechanism. When the pressing mechanism presses down, the sheet can be just bent in the bending die, and the bending effect is good.

[0023] 2. In the utility model, different bending grooves with different depths are arranged on different bending dies, which is convenient for bending the sheet at different angles. The first bending die, the second bending die and the third bending die are connected with the positioning block in a clamping manner, which is convenient for replacing the bending die.

[0030] Embodiment 1

[0031] As Figures 1 - 4 shown, a positioning device for processing square tubes used in a photovoltaic bracket includes a base 1. A workbench 2 is fixed on the top of the base 1. A side support platform 3 is fixed on the top of the base 1 and on one side of the workbench 2.

Fixed blocks 5 are fixed on both sides of the top of the workbench 2 and parallel to the slide grooves 21. The fixed blocks 5 and the pressing mechanism 4 are on the same vertical line. Fixing bolts 51 are threadedly inserted into the fixed blocks 5. Positioning blocks 9 are fixed at both ends of the first bending die 6, the second bending die 7, and the third bending die 8. The fixing bolts 51 pass through the fixed blocks 5 to fix the positioning blocks 9 and make the positioning blocks 9 and the fixed blocks 5 on the same horizontal line.

[0032] A workbench 2 is fixed on the top of the base 1. A side support platform 3 is fixed on the top of the base 1 and on one side of the workbench 2. A pressing mechanism 4 is arranged above the workbench 2, and the pressing mechanism 4 is fixed on the side support platform 3. Slide grooves 21 are opened on both sides of the top of the workbench 2. A first bending die 6, a second bending die 7, and a third bending die 8 are slidably arranged in the slide grooves 21. Fixed blocks 5 are fixed on both sides of the top of the workbench 2 and parallel to the slide grooves 21. The fixed blocks 5 and the pressing mechanism 4 are on the same vertical line. Fixing bolts 51 are threadedly inserted into the fixed blocks 5. Positioning blocks 9 are fixed at both ends of the first bending die 6, the second bending die 7, and the third bending die 8. The fixing bolts 51 pass through the fixed blocks 5 to fix the positioning blocks 9 and make the positioning blocks 9 and the fixed blocks 5 on the same horizontal line. When replacing the bending die, since the fixed blocks 5 and the pressing mechanism 4 are on the same vertical line, only need to align the positioning blocks 9 at both ends of the bending die with the fixed blocks 5, and then screw the fixing bolts 51 into the positioning screw holes 91, so as to fix the bending die directly below the pressing mechanism 4. When the pressing mechanism 4 presses down, it can just bend the plate in the bending die, and the bending effect is good.

[0033] Embodiment 2

[0034] As Figures 1 - 4As shown in the figure, a positioning screw hole 91 is provided on the positioning block 9. A positioning plate 92 is fixed on the top of the positioning block 9 and extends along the side close to the positioning screw hole 91 to the top of the fixing block 5. A calibration block 52 is fixed on the side of the fixing block 5 away from the slider 10. Sliders 10 are fixed on both sides of the bottom of the first bending die 6, the second bending die 7, and the third bending die 8. The sliders 10 are clamped in the chute 21. The pressing mechanism 4 includes a lifting column 41 and a bending knife 42. One end of the lifting column 41 is fixed on the side support platform 3, and the end of the lifting column 41 away from the side support platform 3 is fixedly connected to the bending knife 42. Bending grooves 11 are provided on the tops of the first bending die 6, the second bending die 7, and the third bending die 8. The depth of the bending groove 11 provided on the first bending die 6 is greater than the depth of the bending groove 11 provided on the second bending die 7, and the depth of the bending groove 11 provided on the second bending die 7 is greater than the depth of the bending groove 11 provided on the third bending die 8. The first bending die 6, the second bending die 7, and the third bending die 8 are connected to the positioning block 9 in a clamping manner, which is convenient for replacing the bending die. The fixing block 5 is welded to the workbench 2, making the connection between the fixing block 5 and the workbench 2 firm, so that the positioning block 9 and the bending die can be firmly fixed;

[0035] A positioning screw hole 91 is provided on the positioning block 9, so that the fixing bolt 51 on the fixing block 5 can fix the positioning block 9. A positioning plate 92 is fixed on the top of the positioning block 9 and extends along the side close to the positioning screw hole 91 to the top of the fixing block 5, so that the positioning plate 92 can be flush with the calibration block 52 on the fixing block 5, thereby determining whether the positioning block 9 and the fixing block 5 are on the same horizontal line. By fixing a calibration block 52 on the side of the fixing block 5 away from the slider 10, it is convenient to determine the positioning accuracy between the positioning block 9 and the fixing block 5 through the calibration block 52;

[0036] The pressing mechanism 4 includes a lifting column 41 and a bending knife 42. One end of the lifting column 41 is fixed on the side support platform 3, and the end of the lifting column 41 away from the side support platform 3 is fixedly connected to the bending knife 42. When the lifting column 41 presses down, the bending knife 42 presses down, thereby bending the plate arranged on the bending die, and the bending effect is good. By providing bending grooves 11 on the tops of the first bending die 6, the second bending die 7, and the third bending die 8, when the bending knife 42 presses down on the plate, the plate bends at the bending groove 11, thereby achieving the bending effect.

[0037] Working principle: As shown in Figures 1 - 4As shown, when bending the sheet metal, place the sheet metal on the second bending die 7, and then control the lowering of the lifting column 41 in the pressing mechanism 4, so that the bending knife 42 presses the sheet metal into the bending groove 11 opened on the second bending die 7, thereby forming a bend in the sheet metal at the bending groove 11. When different angles need to be bent, replace the different bending dies, that is, push the second bending die 7 to one side, and push the first bending die 6 or the third bending die 8 to the fixed block 5. Since the fixed block 5 and the pressing mechanism 4 are on the same vertical line, only need to align the positioning blocks 9 fixed at both ends of the first bending die 6 or the third bending die 8 with the fixed block 5, and judge by whether the calibration block 52 on the fixed block 5 is flush with the positioning plate 92 on the positioning block 9, and then pass the fixing bolt 51 into the spiral positioning screw hole 91. Thus, the positioning block 9 is fixed, realizing that the bending die is fixed directly below the pressing mechanism 4. Therefore, when the bending knife 42 squeezes and bends the sheet metal, it can just squeeze the sheet metal into the bending groove 11, and the bending effect is better.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
